Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621370, here are decompositions:

31 + 8621339 = 8621370
61 + 8621309 = 8621370
71 + 8621299 = 8621370
89 + 8621281 = 8621370
127 + 8621243 = 8621370
157 + 8621213 = 8621370
181 + 8621189 = 8621370
223 + 8621147 = 8621370

Showing the first eight; more decompositions exist.
